• A Wi-Fi-connected radio goes out of range.

• An Ethernet-connected radio gets its Ethernet cable disconnected suddenly.

- When you disconnect a radio’s USB programming cable to replace it with a Wi-Fi 

dongle—or vice versa—wait at least 3 seconds after you disconnect the first device 
before you connect the second device.

• Miscellaneous unexpected network events occur.

USB connections can interfere with OTIP connection and disconnection events. Do not 
use OTIP with more than 2 USB-connected radios. (EFJohnson plans to address this 
limitation in a future Armada release.)

Do not try to update a single radio from multiple instances of Armada at the same time. In 
general, radio administrators are expected to coordinate with each other when managing 
radios. OTIP is designed to allow a radio service center to connect to mobile radios 
without running cables.

The user can mute the radio so they do not have to listen to dispatch. (An example is an 
EMT who uses a radio’s call alert feature for notification of an emergency event.) When 
receiving a call alert the radio will automatically unmute and notify the EMT of the event.

If the user has the radio muted, this feature automatically unmutes the radio if certain 
programmable events occur. These events include the reception of a Call Alert, Unit Call, 
or Emergency Call.

Location Services provides GPS location information to the radio user and to network 
administrators using a standardized IP based protocol. For example, a radio can send its 
current location over the radio network and then IP to an application that is mapping user 
locations. That application can also send commands to the radio telling it what data to 
report and when to report it.
